Jinx's hallucinations, or lack of them, are retrospectively a glaring symptom of the problems season two has.
She barely has them, and there's really no reason why that I can think of. Her mental health hasn't gotten any better, and even if it had, these things don't just disappear. And why would you get rid of them? They're a big part of her character. The only thing I can think of that makes sense is the writers just... Forgot. Or someone was laid off who was the real brain behind the operation. Or something that vital to her character was just removed for some incomprehensible reason. And that's what the rest of season two feels like, really. There's so many things that were just forgotten or ignored it doesn't seem like any of the same people were involved at all.
